Reptiles threatened by temperature change

ABC AUSTRALIA

A Central Australian researcher says up to three quarters of the world’s reptiles could become extinct if the temperature changes too much.

Ted Johansen has been nominated for a National Landcare Award for his work looking at the survival of a number of reptiles.

He says there is a correlation between temperature and determination of sex in reptiles.

“Some species in America have been tested and it’s turned out temperature does determine sex,” he said.

“That means one or two degrees difference and if ground temperatures rise and they don’t dig the eggs down further then individual species might have all females or all males.”
